| Abstract: | 相互作用の異なる金属基板上への有機分子結晶薄膜のエピタキシャル成長を行った。炭素と水素以外の元素を含む分子は、部位特異的に基板と共有結合するが、Cu(110)表面上のオリゴアセンの成長は拡張界面準位により特徴付けられ、基板上の第一層は分子が「寝て」いる。一方でBi(001)やシリセンの様な相互作用の小さい表面上では分子が「立って」いる場合と「寝て」いる場合の両方が観察され、分子結晶との格子整合性が重要であることが明らかとなった。 : The epitaxial growth of single-crystalline-like organic multilayer films on selected metal surfaces, chosen to provide either weak or strong interactions at the hybrid interface, has been studied. In particular, while molecules containing heteroatoms form site-specific covalent bonds, the growth of oligoacenes on the Cu(110) surface is characterized by extended interfacial states and a flat molecular orientation in the first layer. On the contrary, for surfaces providing weak interactions like Bi(001) and silicene, both standing and flat orientations occur and are governed by the specific lattice-matching conditions for various crystallographic planes of the thin film crystals. The results provide a detailed understanding of the influence of the substrate beyond the widely studied first layer in achieving epitaxial growth and uniaxial alignment of the grains. |
